[PD] pix_film + particles question

Hi list,

I have a patch with a cube-shaped particle system, with a movie applied on every face of every particle. I have experienced some strange behaviors in the implementation process, so I'm asking the list which is the correct way to do it. I'm using this chain order:

[gemhead] | [part_head] | [part_velocity] | [part_gravity] | [part_source] | [part_sink] | [pix_film] | [pix_texture] | [part_render] | [colorRGB] | [alpha] | [cube]

I previously put the [part_render] between [part_sink] and [pix_film], but the result was that the video was rendered with a speed 10x faster. Am I missing something else? Is there anything else I'm doing wrong? Are there other things to do in order to optimize it?

    Thank you :-)
